You had 180MB remaining out of how much total memory?
If your server has 4GB of RAM, this is less than 5% remaining - a pretty slim 
operational margin.

Jim,

Sorry for not replying sooner... I'm actually on vacation...

Anyhow, I'd checked the system resources...  During the event, there was about 
180 Mb Free RAM...  Don't remember how much was cached ATM, but nothing struck 
me as being constrained...  We've got the system under monitoring, and the 
allocated RAM and page file usage had been stable for over a week (since the 
system was last booted) ...  I certainly was scratching my head as to why I was 
getting an OUTOFMEMORY error when the system really didn't seem to be out of 
memory.

There's 120 GB of free space on the partition (single partition on a RAID1 
disks), so disk space certainly isn't an issue.

If it happens again, I'll certainly grab more granular diagnostic info.

Check your system resources - "ERROR_OUTOFMEMORY" is indicative of a dearth of 
system resources; disk, RAM, etc.
Time for the judicious use of perfmon.

Subject: [isalist] SMTP Send - TMG 0x8007000e ERROR_OUTOFMEMORY

Long story short: On Tuesday evening, I received a complaint from a user about 
an email failing to go through.  Didn't think much of it until a few other 
users complained of a similar issue on Wednesday...  Upon investigation, I 
could see the mails attempting to send (SMTP logs in Exchange 2007), but the 
SMTP conversation would end prematurely  (after DATA, but before the 
corresponding '250 Message Received' response...).  The outbound SMTP queue was 
backed up with 4.4.2 transient failure errors, but not all messages were 
failing to send...

After digging, in the TMG logs I noticed corresponding  "Closed Connection" 
events with the result code "0x8007000e ERROR_OUTOFMEMORY" for the failed SMTP 
connections.   There were no other anomalous issues with the TMG server that I 
could find (no memory pressure, no disk or CPU problems, nothing out of the 
ordinary in the event logs, etc).  I stopped and restarted the firewall 
service, and the backlog of email flushed through and things have been running 
smoothly again since...

Anyone run into this issue before?  Most of the references I find with the 
error code relate to Outlook problems...  Hence Google or Bing aren't being 
very helpful...
